FOR ATTAGEING A TIRE-INFLATING DEVICE TO A ROAD-VEHICLE ii /"HEEL.

Patented A11 25, 1914.

Application filed May 23, 1914. Serial No. 840,651.

means for attaching to a road vehicle wheel in a detachable manner a tire-inflating device of the kind which is operated by the rotation of the said read wheel so as to pump air into a leaking, deflated or damaged tire.

inflating devices of this kind are described in my prior Patent Specification No. 97 2050 and in the specification of my pending ap plication, Serial No. 787676 filed September Hitherto these tire-inflating apparatus have been attached to the hub or to the spokes of the vehicle wheel. According to the present invention 1 support the frame carrying the pumping mechanism, from the rim or felly of the wheel by direct connections be tween the frame and the rim or felly. I propose to employ arms which are jointed, hinged, socketed or otherwise secured, preferably in a pivotal manner, at their inner ends to the aforesaid frame and at their outer ends are detachably or removably anchored to the rim or felly. These arms are with advantage made adjustable as to length and the anchoring means mav take, for example, the form of hooks or claws, riveted or similarly secured to the rim, or these anchoring means may utilize the existing se curit bolts of the timer transverse belts in the case, for instance, of the well known Michelin detachable rim. I

Preferably I employ only three arms, two of these being arranged comparatively close together and the third acting'in opposition to the other two, so that the frame can be rapidly mounted and tensionedin position.

By means of this invention the attachment of the inflating device in position is made in a simpler and more positive manner and is unaffected by centrifugal action due to the rapid rotation of the road wheel. Moreover there is obtained an attachment which is more easily and ex editiously secured. in place or removed, without preventing access to the wheel hub or hub-cap, and better adapted to support the pumping device in its operative position, viz. at the side of the Fig. 1 on line A.A. Figs. 8, at and wheel and around the hub-cap without connection to the latter.

I may also, if desired, provide the frame with a centering cone or funnel to guide the frame over the hub or hub cap when it is being secured in place.

The present invention is hereafter described with reference to the annexed drawings, in which Figure 1 is an elevation of the frame fitted with three arms and seen from the rear or inner side. Fig. 2 is a sectional elevation of 5 are on a larger scale and of these Figs. 3 and a show a duplex claw device, while Fig. 5 is a sectional elevation showing the duplex claw device engaged by the arm-fitted sleeve. Figs. 6 and 7 show a modified form in which the inner end of the arm. is hinged or ournaled to the frame or base plate. FigsS, 9 and 10 are cross sectionsrepresenting types of wheels fitted with claw devices. Figxll is a part section on a larger scale showing the dust excluding device. Fig. 12 shows a road wheel fitted with the pumping arrangement secured in position by means of the three point attachment, the cover plate being removed. 1

The central frame is indicated at a on which are supposed to be mounted the pumping devices and the connection to the valve of the tire of the road wheel. For a fuller description of these pumping devices I refer to the specification of my pending application Serial No. 7876??) filed September 2nd 1913. The pump cylinders are shown in Fig. 12 at 10, the piston rods at 2T, cranks 26 and toothed gearing 24:: 36 is the union for the compressed air pipe 37 leading to the tire valve 38.

The frame a has a cut out central portion a through which the hub cap of the wheel may pass and is preferably provided with a counterbore o The frame is provided at its rear (that is the side nearer the plane of the wheel) with an outstanding flange 0 and this flange is perforated at d to allow the passage therethrough of the three arms I). The latter are provided with ball or knob heads 6 which prevent the arms from being drawn wholly through the perforations (Z. These heads may, as shown, have projecting pins 9 to prevent the rotation of the arms.

The arms Z) are arranged not equidistantly around the wheel but two of them are comparatively close together so that these two act in opposition to the third arm.

The arms 6 are screw-threaded on their outer extremities as at e, and the two arms which are closer together are shown provided with sleeves or nuts f having trunnions or wings f adapted to be engaged by a duplex out-turned claw device 9 which is riveted or otherwise attached to the rim or folly of the wheel: see Figs. 8, 9 and 10. The claw device is clearly shown in Figs. 3 and 4 with the cut-away middle portion 9 for the passage of the screw-threaded part c. The third arm is shown fitted with a tensioning or contractible device it adapted to be screwed upon the extremity e and having at its outer end a swiveling or freely rotatable head 2' fitted with cross-bars, trunnions or Wings 2' whereby it may be engaged with a third duplex claw device 9.

The screwed sleeves or nuts f of the two juxtaposed arms Z) having been adjusted and engaged with their claw devices 9 9' so that the cross bars 7 lie snugly in the two duplex claw devices g, the swiveling head i;

of the tensioning device is engaged with its claw device 9 and by means of. the device h the three-point attachment may be tensioned and fixed in place upon the wheel. The screw-threaded portions 6 of the arms 5 are shown provided. with looking nuts Z.

rims or fellies of slightly different diame- "ters.

In Figs. 8, 9 and 10 I have shown the claw g secured to respectively a wire wheel,

a wooden wheel, and a steel wheel.

The claw device may be fastened by, screws, riveted or otherwise secured to the rim or felly of the wheel and it is shaped to lit the rim or telly according to the type and size of rim or telly to which it is applied. Diiierent forms of rims and wheels are shown by way of example in Figs. 8, 9

and 10.

It is to be understood that if desired each of the arms Z) may be fitted with a tensioningdevice such as k.

In orderto prevent the ball-headed arms f lling back through flange 0 when the attachment is removed from the wheel, a guid ing cone m may be employed. This cone m is riveted or otherwise attached to the irame a and is shown continued for a small distance through the central aperture a 1n the frame a. lit serves to assist in passing l shown in Figs. 6 and 7, the arms I) may be secured to the frame by hinged or pivoted connections such for instance as U-shaped brackets 0 upstanding from plates 0 rivet ed or otherwise mounted on the frame and having crosspins or pivotal bolts 29 passing through the inner ends of the arms and the brackets 0. In this case the perforated flange a may be dispensed with.

lVhere the arms are thus hinged orpivoted to the frame they can be folded over and the total length thus reduced when the device is removed from the wheel; and where (as shown in Figs. 1 and 2) the-ballhead arrangement Z1 is used the fixingof the arms Z; to the claws and their engagement therewith, is facilitated since the arms are permitted a slight lateral movement at their extremities.

At 8 in Fig. 11 T have shown a packing expression jointed in the description and claims, I mean pivoted, hinged, lrnuclrled or prov1ded with a ball and socket oint, for obviously the inner ends 01" the arms may be secured to the frame in accordance with this invention in various ways.
